| Abstract: | In a certain area, height anomalies usually have certain geometric relativity. GPS height fitting uses this principle to extract normal height, in the paper, the principle and superiority of curved surface spline func-tion interpolation are discussed, the GPS height fitting is carried, and the known points are validated, as re-sults,it is reliable, and the method is feasible and effective,has a certain scientificalness and practicability. |
